“I remember, yes. Buffoonery. A burlesque of hospitality. Do you mean you are abetting it?”

“I wouldn’t say abetting it. A man I know named Austin Byne phoned and asked me to fill in for him because he’s in bed with a cold and can’t go. Anyhow, it will give me a fresh outlook. It will harden my nerves. It will broaden my mind.”

His eyes had narrowed. “Archie.”

“Yes, sir.”

“Do I ever intrude in your private affairs?”

“Yes, sir. Frequently. But you think you don’t, so go right ahead.”

“I am not intruding. If it is your whim to lend yourself to that outlandish performance, very well. I merely suggest that you demean yourself. Those creatures are summoned there for an obvious purpose. It is hoped that they, or at least one of them, will meet a man who will be moved to pursue the acquaintance and who will end by legitimating, if not the infant already in being, the future produce of the womb. Therefore your attendance there will be an imposture, and you know it. I begin to doubt if you will ever let a woman plant her foot on your neck, but if you do she will have qualities that would make it impossible for her to share the fate of those forlorn creatures. You will be perpetrating a fraud.”

I was shaking my head. “No, sir. You’ve got it wrong. I let you finish just to hear it. If that were the purpose, giving the girls a chance to meet prospects, I would say hooray for Mrs Robilotti, and I wouldn’t go. But that’s the hell of it, that’s not it at all. The men are from her own social circle, the kind that wear black ties six. nights a week, and there’s not a chance. The idea is that it will buck the girls up, be good for their morale, to spend an evening with the cream and get a taste of caviar and sit on a chair made by Congreve. Of course—”

“Congreve didn’t make chairs.”

“I know he didn’t, but I needed a name and that one popped in. Of course that’s a lot of hooey, but I won’t be perpetrating a fraud. And don’t be too sure I won’t meet my doom. It’s a scientific fact that some girls are more beautiful, more spiritual, more fascinating, after they have had a baby. Also it would be an advantage to have the family already started.”

“Pfui. Then you’re going.”

“Yes, sir. I’ve told Fritz I won’t be here for dinner.” I left my chair. “I have to see to something. If you want to answer letters before lunch I’ll be down in a couple of minutes.”

I had remembered that Saturday evening at the Flamingo someone had spilled something on die sleeve of my dinner jacket, and I had used cleaner on it when I got home, and hadn’t examined it since. Mounting the two flights to my room, I took a look and found it was okay.

I was well acquainted with the insides of the Grantham mansion, now inhabited by Robilottis, on Fifth Avenue in the Eighties, having been over every inch of it, including the servant’s quarters, at the time of the jewellery hunt; and, in the taxi on my way uptown, preparing my mind for the scene of action, I had supposed that the pre-dinner gathering would be on the second floor in what was called the music room. But no. For the mothers, the works.

Hackett, admitting me, did fine. Formerly his manner with me as a hired detective had been absolutely perfect; now that I was an invited guest in uniform he made the switch without batting an eye. I suppose a man working up to butler could be taught all the ins and outs of handling the hat-and-coat problem with different grades of people, but it’s so darned tricky that probably it has to be born in him. The way he told me good evening, compared with the way he had formerly greeted me, was a lesson in fine points.

I decided to upset him. When he had my hat and coat I inquired with my nose up,” How’s it go, Mr Hackett?”

It didn’t faze him. That man had nerves of iron. He merely said, “Very well, thank you, Mr Goodwin, Mrs Robilotti is in the drawing-room.”

“You win, Hackett. Congratulations.” I crossed the reception hall, which took ten paces, and passed through the arch.

The drawing-room had a twenty-foot ceiling and could dance fifty couples easily, with an alcove for the orchestra as big as my bedroom. The three crystal chandeliers that had been installed by Albert Grantham’s mother were still there, and so were thirty-seven chairs—I had counted them one day—of all shapes and sizes, not made by Congreve, I admit, but not made in Grand Rapids either. Of all the rooms I had seen, and I had seen a lot, that was about the last one I would pick as the place for a quartet of unwed mothers to meet a bunch of strangers and relax. Entering and casting a glance around, I took a walk—it amounted to that—across to where Mrs Robilotti was standing with a group near a portable bar. As I approached she turned to me and offered a hand.

“Mr Goodwin. So nice to see you.”

She didn’t handle the switch as perfectly as Hackett had, but it was good enough. After all, I had been imposed on her. Her pale grey eyes, which were set in so far that her brows had sharp angles, didn’t light up with welcome, but it was a question whether they ever had lit up for anyone or anything. The angles were not confined to the brows. Whoever had designed her had preferred angles to curves and missed no opportunities, and the passing years, now adding up to close to sixty, had made no alterations. At least they were covered below the chin, since her dress, pale grey like her eyes, had sleeves above the elbows and reached up to the base of her corrugated neck. During the jewellery business I had twice seen her exposed for the evening, and it had been no treat. The only jewellery tonight was a string of pearls and a couple of rings.

I was introduced around and was served a champagne cocktail. The first sip of the cocktail told me something was wrong, and I worked closer to the bar to find out what. Cecil Grantham, the son of the first husband, who was mixing, was committing worse than murder. I saw him. Holding a glass behind and below the bar top, he put in a half-lump of sugar, a drop or two of bitters, and a twist of lemon peel, filled it half full of soda water, set it on the bar, and filled it nearly to the top from a bottle of Cordon Rouge. Killing good champagne with junk like sugar and bitters and lemon peel is of course a common crime, but the soda water was adding horror to homicide. The motive was pure, reducing the voltage to protect the guests of honour, but faced with temptation and given my choice of self-control or soda water in champagne, I set my jaw. I was going to keep an eye on Cecil to see if he did to himself as he was doing to others, but another guest arrived and I had to go to be introduced. He made up the dozen.

By the time our hostess led the way through the arch and up the broad marble stairs to the dining-room on the floor above, I had them sorted out, with names fitted to faces. Of course I had previously met Robilotti and the twins, Cecil and Celia. Paul Schuster was the one with the thin nose and quick dark eyes. Beverly Kent was the one with the long narrow face and big ears. Edwin Laidlaw was the little guy who hadn’t combed his hair, or if he had, it refused to oblige.

I had had a sort of an idea that with the girls the best way would be as an older brother who liked sisters and liked to kid them, of course with tact and refinement, and their reactions had been fairly satisfactory. Helen Yarmis, tall and slender, a little too slender, with big brown eyes and a wide curved mouth that would have been a real asset if she had kept the corners up, was on her dignity and apparently had some. Ethel Varr was the one I would have picked for my doom if I had been shopping. She was not a head-turner, but she carried her own head with an air, and she had one of those faces that you keep looking back at because it changes as it moves and catches different angles of light and shade.
